Weed and Feed is one of the most commonly used weeding products being used by lawn owners today. These are the products which are sold in a bottle, attached to a hose and then sprayed onto the lawn with the supposed ideal of both fertilising and killing weeds in our lawns. But what is the effectiveness of these weed killers in our lawn care?
Oxalis can be a very difficult weed to kill, it is highly resistant to weak herbicide products such as the almost useless Weed and Feed types of weed killers. With prior knowledge of the difficulty in killing Oxalis, and knowledge and planning our weed control practices, we'll get the job done very effectively and with the least amount of resistance from this tough Oxalis weed.
Petty Spurge is an abundant but easily killed weed in home lawns and gardens in Australia. The weed has 1 - 4 stems of a reddish colour, and has pale green leaves and similar looking flowers which are often indistinguishable from the leaves. The stems can grow up to 10 cm in height from the base of the plant.
This lawn weed isn't a very strong competitor and can only survive by being an opportunist, Petty Spurge could never establish in a well cared for lawn but will establish itself in bare areas of turf, open garden beds, paths and anywhere else it can plant itself where it doesn't need to compete for space or resources with lawns or other plants.
Nutgrass and Mullumbimby Couch are very tough weeds which are extremely difficult to control and kill. Once established in a lawn they will need to be treated thoroughly and properly in order to completely remove them.
Nutgrass and Mullumbimby Couch are extremely similar in their appearance, with weed treatments being the same, as well as belonging to the same weed family, for this reason we will refer to both as Nutgrass.
Wireweed grows flat to the ground sending it's tough runners in all directions, it is a common weed in most regions of Australia which can grow and seed all year. The weed is an annual but also has the ability to hibernate for the Winter and re-emerge for a second season of growth.
The tough stems of Wireweed are a dark green colour often with a purple hue. Along the stems grows masses of tiny white flowers which are barely noticeable as flowers until a closer inspection is taken.
Burr Medic is another common weed in many home lawns and gardens, it comes from a family of weeds called Medics, which are all quite common and all look very similar. The differences are irrelevant and treatment is the same across all weed types.
Burr Medic grows long purple-green stems which creep along the ground, they have trifoliate leaves with three sections to each leaf, in much the same way as Clover and Oxalis have. Burr Medic develop yellow pea shaped flowers along their stems and many small green-brown burrs which are often soft and covered in soft prickles.
